Specification of Letters Patent.

Patented Dec. 26, 1915.

Application filed December a, 1914. serial No. 875,196.

To all whom it may concern t Be it known that I, EDGARD FRANIUGNOUL, a subject of the King of Belgium, residing at 196 Rue Gretry, Liege, Belgium,lhave nvented certain new and useful improvements in rlubings for Boring; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to ywhich it appertains to make and use the same, reference being had to the accompanying drawings,`and to letters or figures of reference marked therein, which form a part of this specication. v

rThis invention relates to the boring Eor sinking of holes in soil, such as is necessary in constructing pile foundations and the like, the chief object being to provide an apparatus which will permit of heavy `blows being imparted thereto at the commencement of the operation, and thereby enable the bor ing or sinking of holes in hard soil to be effected in lesstime than has heretofore been possible with existingapparatus of this type. According to this invention, the apparatus comprises a plurality of telescoping tubes whiclrare adapted to be driven into the soil in the collapsed condition and subsequently operated in such a manner that the inner tubes areextended one after the other until the whole series is fully extended. In this manner the exterior tube first assumes a delinite position in the soil and subsequently serves to guide the adjacent inner tube during the extension thereof, in completing the sinking or boring of the hole. Each tube will in turn serve as a guide for the adJacent inner tube andin this manner an effective support and guide is aiiorded for all the sections of tubing during the sinking operation. The power for operating the apparatus may be derived from a monkey which 1s adapted to impart its blows in a regulated manner to the sections of tubes comprised in the apparatus so as to obtain the sequence ofextensions referred to above. The upper ends ofthe telescoping tubes may be provided with collars or rings which when the tubes are in the collapsed condition are brought together and adapted to form a seatingfor a ring which in turn supports an anvil or top piece which receives the blows of the monkey. The initial portion of the sinking operation is eii'ected with the ring and anvil in the aforesaid position andthe subsequent portion of the sinking operation is eli'ected Yby withdrawing' the ring and allowing the anvil to rest on the collars carried by the inner sections of tubes. ln order to allow ofthe extension of the inner tubes the external diameter of the anvil is made a working it in the interior of the outer tube of the apparatus, and inl this way it is free to move within the same and effe-ct the extension or displacement of the said inner tubes.

The innermost tube ofthe apparatus may be provided at its lower end'with a boring head or plug and between this latter member and the anvilat the upper end of the apparatus, a suitable rod or distance piece may be arranged. A rod may be provided within the interior of the apparatus so as to extend through thesame and serve as a guide for the monkey during its operation. In some cases the boring head at the lower end ofthe inner tube of the apparatus may beextended in such a manner as to pass up within the interior of the tube into a positiony that will permit of the same being struck by the hammer simultaneously with the upper edge kof thetube.

In order that the said invention may be clearly understood and readily carried into effect, I will now proceed to describe-the same more fully with reference to the accompanying drawing in which Figure 1v is a ksectional elevation taken through the axis of the apparatus showing the position of the parts during the first periodrofthe sinking operation. Fig. 2 is a partial view of the apparatus in longitudinal section showing the position of the parts during the second period of the operation. Fig. 3 is a side elevation of a ring employed with the apparatus. Fig. 3a is a plan there of. Fig. t is a sectional elevation of a modified form of the apparatus showing the parts during the first period of the sinking operation. Fig. 5 is a similar view showu ing the parts during the second period ofthe operation'.

Referring to the arrangement shown in Figs. 1 to 3, the apparatus comprises two telescoping tubes 1 and 2,y which are provided at their upper ends with collars or ribs 3 and 4 which when the tubes are in the collapsed condition lie yadjacent to each other as shown in the drawing. These collars or ribs form a seating for a ring 6, Fig. 3, which is built up of two elements 6&6 eachk provided with lugs having holes 18 into which pegs or pins may be inserted to connect the two elements together. manner the rings may be ring 6 is arranged an anvil or top piece 11 which is provided with an annular enlargement 12 of external diameter somewhat smaller than the internal diameterl oi' the outer tube 2 of the apparatus, so as to make said enlargement a working t therein.

rlhe lower end of the inner tube 1 is closed by a boring head or plug 8 which is capable of sliding in said tube and provided with a reduced portion 8 similar to the plug disclosed in the specification of my prior Patent No. 1,0al8,304r. A central guiding rod 10 passes throughy the plug S and distance piece 13 in a similar manner to the arrangement shown in the aforesaid prior patent. rlChe rod 10 passes through the anvil 11 at the upper end ot the apparatus and is extended beyond the same to serve as a guide for the monkey during its movements.

During the initial period of the sinking operation, the parts ofthe apparatus are in the position shown in Fig. 1 and the blows oi the monkey 7 are imparted to the anvil 11 and in turn through the rings 6 to the collars 3 and 1 carried by the upper ends of the telescoping tubes. 1t will be observed that the tubes are in their collapsed position and they are driven into the soil in this condition until the outer tube 2 has been sunk into the soil a suflicient distance. llifhen this has been effected the ring 6 is removed so as to allow of the annular venlargement 12 of the anvil to rest on the collar L1 of the inner tube 1.'A lf blows are now imparted to the anvil this member will serve to displace the inner tube with respect to the outer tube 2 and in this manner complete the second period of the sinking or boring operation. As previously mentioned the annular enlargment 12 of the anvil is a working lit in the interior of the outer tube 2 so that the displacement of the anvil therein is readily effected. 1t will be observed that during the initial period of the sinking operation, the tubes are in their collapsed condition, and consequently are able to withstand harder blows from the monkey than they would be n' in the extendedv condition. Vhen the collapsed tubes have been sunk to the desired depth the outer tubewill serve as a guide and support for the inner tube 1 during its subsequent sinking into the soil.

1n the arrangement shown in Figs. L1 and 5, the reduced portion 14 or" the boring head is extended in such a manner as to bring the upper end of the head into a position to receive the blows of the monkey 16. The latter member is provided at its upper end with an enlargement 17 which is a working tit in the interior of the outer tube 2 of the apparatus. In this manner the Vmonkey n1 this readily detachedL from the apparatus when desired. Y On the;

's adapted to impart its blows directly to he upper end of the inner tube 1 and at the rame time strike the upper end of the boring nead 8. 1n this arrangement the anvil 11 used in the prior arrangement is dispensed ,with as the blows are directly imparted to the inner tube or tubes by the monkey 16. During the initial period of the sinking operation the ring 6 is employed as previously described and after the initial sinking operation has beenv etliected the ring is removed so as to allow the monkey to pass within the outer tube and impart its blows to the upper end of the inner tube.

lt will be understood that the apparatus may comprise any number of concentric tubes and in this case a corresponding number of rings 6 would have to be provided so as to permit of the various sections of tube being sunk one after the other into the soil. 11'? desired, the rings 6 may be connected to the anvil or top piece 11 or to the monkey 17. 1n this case a number of anvils 11 or monkeys 17 would have to be employed with the apparatus having enlarged bases of sizes corresponding to the respective rings. rlhis arrangement would be extremely useful when the invention is applied to tubing having more than two sections and dithculties would be avoided which would otherwise result from the necessity of withdrawing the rings driven with the tubing into thesoil.
